EF420 Flood and Drain system

The EF 420 Hydroponic Flood and Drain growing system is an ideal system for a 600w or 2x 400w lighting units.

It is a recirculating, modular system with the nutrient tank directly beneath the flood tray to allow as much 'head height' as possible for your plants.The system is flooded as often as you decide (2-6 times in daylight hours) ideally utilising an Imperium Feed Duration Controller or 'Plus Controller which offers complete, precise control of a stable nutrient feed, or at the very least a quality segmental or digital timer

Plants are grown in 13cm square pots filled with clay pebbles, or the growing tray can be filled entirely with clay pebbles, but be aware of your flooding depth to ensure pebbles are not pushed up and out of the tray!
